1 out of 5 eggsShipping Woes

This review is from: XFX P1-850B-BEFX 850W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply

Pros: I'll be sure to update this once I get a unit that's not DOA, but I'll say the modular design is nice and setting it up/and taking it back out was fairly quick and easy (hence 2 eggs even being DOA). It's a minor qualm but the cable ends are fairly sharp. Not uncommon with PSU's, but when you're plugging in and awkward place it'd be nice if a company took a first step and just smoothed those edges out a little.

Cons: Unit arrived DOA most likely due to the dented packaging and water damage. The box must of been beaten so hard the packaging on the inside was open... This hasn't been the first time with Newegg, but this is a first where the product is DOA due to shipping. Newegg please review your shipping policy. I think when I get a box mauled I shouldn't have to pay my own shipping to send it back to you.

Manufacturer Response:

Hello,

We're sorry you had issues with the shipping company. However, this is not a Newegg or XFX issue, this should be filed as a claim with the shipping company immediately, with pictures.

It is important to contact Newegg for the replacement, but more important to get the claim started.

For more information, please contact us at neweggsupport@xfxforce.com.

5 out of 5 eggsMore like a Platinum 850W

This review is from: XFX P1-850B-BEFX 850W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply

Pros: Compact size for its class, my old ABS Labs TAGAN BZ 700W PSU was bigger than this one.

Extremely, and I do mean EXTREMELY solid and clean power draw to the system, voltages are literally within a 2% margin and that is going into the Platinum ratings.

Comes with all the necessary cables to attach just about any peripheral you need and will still have more slots available if you actually need to order more cables from XFX.

All the cables are in a MATTE Black finish and minimally impede airflow when using wire management in your case if available.

These cables were able to easily reach all spots on my ANTEC 1200 V3 Full Tower, so if you have a full tower and are concerned about wire length, don't be, they have this covered very well.

You also get a thick ferro-spiral wire braided (interior) 16AWG rated power cable with this that is pretty heavy duty and should help give you clean power, combine this with a Monster Power Center which has an AC noise filter in it and your PC will be running cleaner than you after a 30 minute shower.

There are tons of personal and professional reviews about this PSU and not one of the professional reviews gave it bad remarks, please be sure to check for the BEFX version as this (as of this review) is the latest version available and is substantially different than its predecessors.

Cons: I didn't buy the 1000W version.....

On a more serious note, there are no real cons here at all, this is really all you can ask for if it meets your +12V Amp ratings and the Wattage you are seeking. In the 700-900W range this PSU is the end all be all of all the PSU's currently available.

Other Thoughts: All my research into this product prior to my purchase revealed that this is an XFX Rebranded Seasonic, and the reviews on the Seasonic that this is based on are top notch.

This PSU does come with a standard 5 year warranty, which is already awesome, but for more awesomeness REGISTER THIS PSU on XFX's website within 30 days to get a FREE upgrade to a LIFETIME WARRANTY! Now that is awesome!

Next time I need a PSU upgrade I will be looking to this line of PSU's from XFX!

This review is from: XFX P1-850B-BEFX 850W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply

Pros: Build quality, efficiency, cables, fully modular. Everything looks pro

Cons: None thus far

Other Thoughts: Great PSU. Going to use this to power an SLI setup with SSD/HDD combo, DDR3 etc. Should be plenty of power to satisfy my components.

5 out of 5 eggsDoes what is advertised

This review is from: XFX P1-850B-BEFX 850W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply

Pros: full modular, gold certified so it's guaranteed to give 90% of the advertised power, supplies sufficient power for 6 fans, a geforce gtx 770, msi gaming motherboard with a unlocked i5 haswell processor and plenty of plugs for extra harddrives or disc drives. power connectors that are not required will not be on the psu.

Cons: the plugs will barely reach the connectors on the motherboard and as such will be problematic for those who like to tie down their cables or run them through holes on the other side of the motherboard.

Other Thoughts: the power connectors for the harddrive/disc drive would benefit from an extra inch b/w each plug for a full chassis environment, especially for those with multiple drives.

This review is from: XFX P1-850B-BEFX 850W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply

Pros: Worked like a champ on my amd 290

Cons: My amd got power hungry and melted one of the plugs and socket for the psu to gpu cable.

Other Thoughts: Was able to rma gpu and psu both returned in a decent amount of time. As far as getting a response back from support ticket and people blasting xfx for support, I was delighted to get my new psu, cables and all in less than a month.

5 out of 5 eggsAwesome PSU, Modular cables... Not so much.

This review is from: XFX P1-850B-BEFX 850W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply

Pros: This is a rebranded Seasonic. It's got an extremely consistent output, fully modular, 5 year warranty and is Gold rated.

All black flexible ribbon cables.

Cons: Just wish XFX would sell an extra set of modular cables as most of the cables are at least 6 inches too long for my mid-size ATX case. I would love to purchase another set and cut, crimp, and sleeve these cables for a perfect fit.

The GPU cables are all 6+2 pin and have 2 plugs per cable. I understand that this PSU is rated for and can accommodate Multi-GPU setups but if you are only running a single card like me, you'll have an extra plug hanging inside your case. With my GFX card (EVGA nvidia 780 reference with ACX cooler) the extra plug on the cable points directly to one of the fans on the card, so I had to bend the cable to point straight down.

Manufacturer Response:

Thank you for the great review. We are happy you are pleased.

Pros: Worked great while it worked and didn't take any of my equipment with it when it died.

4 out of 5 eggsGreat PSU silent and efficient

This review is from: XFX P1-850B-BEFX 850W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply

Pros: 1. Full modular
2. Hybrid or Normal Fan regardless which you choose the fan is silent
3. Deliver the watts you need I am usint this on a GTX 780 SLI no problem here

Cons: I got an open box from newegg that's why I took 1 star I think they send me a refurbish one when it is listed as new and paid it for like a brand new price I didnt bother to sent it back its to much thing to do for me hope this PSU will last long

Other Thoughts: It could have a LED as a plus and have some modular color coded not only pure black

Manufacturer Response:

Thank you for the great review! If you ever have an issue with this PSU, or a question, please contact our XFX Support team at neweggsupport@xfxforce.com.

5 out of 5 eggsso far so good.....

This review is from: XFX P1-850B-BEFX 850W ATX12V 2.2 & ESP12V 2.91 SLI Ready CrossFire Ready 80 PLUS GOLD Certified Full Modular Active PFC Power Supply

Pros: Nice PSU.....basically a rebranded Seasonic. Plenty of cables and fully modular. Good price for a budget builder. And the gold rating doesn't hurt either. Enabled my to overclock my FX8350 to 5.0 GHz with easy and piece of mind. Like the hybrid switch. Allows for a quiet operation.

Cons: Cables are ugly gloss black. I'm a big fan of red cables and red builds. other than that not much else.

Other Thoughts: If your looking for a cheaper Seasonic this is the one. XFX seems to have a good thing with Seasonic on this one. Almost bought the 1050watt but didn't need that much power as I have a lower end gaming rig.

Manufacturer Response:

We're glad its working great for you. We appreciate the positive review. As always, if you have any questions, please contact us at neweggsupport@xfxforce.com. Play Hard!
